Burma's opposition leader, Aung San Suu Kyi, is safe despite the roof of her home, where she is being held under arrest, being blown off, according to a neighbour.

The death toll could be as high as 600,000, according to an interview with an unnamed government official quoted by blogger Moethee Zun. He says 180,000 were killed in Lutbutta alone. A further 90,000 died in Phyar Pone township, and 80,000 in Bogalay, according to the source.

The international development secretary, Douglas Alexander, has begun to give a statement to the House of Commons about the crisis. "The situation is becoming increasingly perilous," he said. It was vital that aid workers get access, he added and said the UK government was lobbying the Burmese to allow access.

"It is important that the Burmese government accepts all offers of international help offered to it. This is a grave crisis on a scale that has not been seen since the 2004 tsunami," Alexander said.

Burmese authorities must give assurances that they won't profiteer from the crisis, says Amnesty International.

Benjamin Zawacki, the human rights organisation's Burma researcher, said: "Government red tape in providing visas is costing lives, while some donors are delaying aid in the fear that it will be siphoned off to the army. The government should now provide access and assurances to international relief workers."

"Every day of delay is costing lives. If the regime won't give permission for aid, the international community must deliver it anyway. We can't stand by and let thousands more die," said its director, Mark Farmaner.

He added: "The government must also send the British Navy off the coast of Burma, ready to deliver aid by helicopter."

In this clip posted to YouTube, Al-Jazeera contrasts what it has seen in Burma with the way state TV is reporting the crisis. Listen out for a Burmese newsreader saying: "Foreign correspondents have entered Myanmar illegally and broadcasted fabricated news and incorrect news, very often with the help of anti-government associations".

"People have nothing to drink so they drink water from the creeks and rivers. So that is how the outbreak began. These waterways are dirty because they are littered with bodies and animals. The survivors know the water is dirty, but they have no other choice and have had to drink the dirty water. That's how they contracted cholera.

"This is the time for us to stock up on cholera medicine for the possibility of an outbreak in the near future. However, we do not have enough medicine," the unnamed worker said.

A fist fight broke out in Rangoon when locals saw water being delivered to the homes of council members and military officers, according to Awzar Thi's translation of a post from Khitpyaing.

"It's been six days since the cyclone Nargis struck and the situation is getting worse day by day due to the decomposed animals and humans lying around the affected areas. In recent days, we had witnessed the generosity of the world as the humanitarian aid in millions of dollars. But it is very sad to find out that Burmese government is hesitating to grant visas to UN aid workers and NGOs in the name of politics," says blogger Soe Moe.

The post adds: "I was so surprised to see that dead people being dumped into the rivers. It will endanger the people who are living along the river bank with deadly diseases."
